nx'cAvA-'ron 4Specification of Letters Patent No. 13,680, dated October 16, 1855.

To all lwhom z't may concern.' s

`Be it known that I, BENJAMIN HANoooK,'

the machine and Fig. 2 an enlarged viewof the dumping scoop. l

The letters of reference indicate the same parts in thedit'ferent figures wherever they pccur.

The vnature'of my invention c nsists in the construction and arrangemen of parts of the dumping scoop as herein described and secondly in the combination of the scoop with the adjust-able frame as herein described for the purpose of'facilitating the -application of horse or other power thereto.

I' construct a framework of three pieces (a) arranged horizontally in the form o't an isoscees triangle. vThe two forward are supported by uprights, (b) resting `upon wheels (o). are connected'by a cross piece (d). The apex of the ltriangle (which is at the rear f of the machine) is supported by anfupright (e) -longer than the others, and also furnished with a wheel (f) resting upon the bottom of the excavation g, it is'made adjustable -its/ length by-means of bolts, which arernade to slide in the slot a', when the nuts aref loosened. From each of the ing at the point h, where the block 7c is sus- Mpended. An upright piece (Z) with a sheave in its lower extremity passes through' a' staple in the forward part of the machine, where it is'secured--by a pin.` It can be raised inthe staple when required. The framework is stilfened by suitable braces.

The excavating scoop Fig. 2 is composed of the scoop proper m, with its shaft o, pivoted at D to the slotted suspension rod q. A lever (9) is pivoted to the shaft o,

-and bent at its forward end into a segment of a circle the center of which is at spring (s) and the segment being furnished with notches which engage on the pin t. The handle n, is also pivoted at p, and carries a sliding ring u, to hold4 the shaft o,

These uprights p, the rear end being held up by av down to the lhandle n when in use. Td'

the top of the` rod g, a rope is, secured which passing through the block la and down through the sheave in t, is attached'fto the horse or other power employed. Double blocks, and tackle 'can be substituted forY the single block. 4 I

The machine is shown in Fig. las arranged for digging a trench or ditch of moderate depth. It is secured in position vagainst the force of the working power, by

inclined irons (o) which are force(l into the' ground through staples in the upright Z,'or in any other-'convenient manner.. ,A laborer having -adjusted `thepitch of the' scoop by placingthe proper notch of the segment upon the pin t, forces the scoop against the earth to be removed, by means of the )handle n. The horse is put in Amotion ,and by means of the rope ralses the scoop filled with earth to the desired elevation. Then if the excavation is not too deep he (retaining his hold upon the handle n) slips'back the ring which holds the, shaft o, to the handle, bears the scoop overto the place where its load is to be discharged, and presses on the handle of the lever r, thus elevating the segment, end releasing it from 1the pin, he lets go'his hold upon the lever. The load is then dumped by the sudden tipping of the scoop m. V Vl1`env it becomes necessary to-move the machine forward the irons v are raised and thel team exerts `its power for that purpose. When it is to beremoved from place to place the upright e, is slid up until its wheel f is brought on a level with the others, and

there secured.

My machine is best adapted for narrow excavations of varying depth, such s ditches, and trenchesl for pipes, sewers,

and admitsof a` great saving in manual labor, by the substitution therefor, of the power of horses',/ ortable steam engines, &c., in a convenien manner.' l.

Having thus fully described my improved machine, what I claim as my invention and desire to secure by Letters Patent is- '1. The dumping scoop constructed, ar-I ranged, and operated substantiallyas' described, an l for the.purpose speclfied.

2. In c bination with the ab'ove, the

movable, and adjustable frame as hereinI described yfor the purposes-set forth. I
